reference being bad to the accompanying,

drawings, forming a part thereof.

The purpose of this invention is to provide an improved means of mounting a bumper on an automobile frame of the type and character which has longitudinally extending side bars and a connecting cross bar at the end of the side bars, being particularly designed for a rear bumper on a car of the Ford type. lit consists in the elements and features of construction shown and described, as indicated in the claims. g

In the drawings Figure 1 is a plan VlW of a portion of the chassis body of a car having a bumper mount embodying this ,invention applied thereto.

Fig. 2 is an elevation of the same, looking in the direction of the arrow on Fig. 1.

Fig. 3 is a section at the line, 3--3, on Fig. 2.

Fig. 4 is a section at the line, l-d, on Fig. 4:,

In the drawings, 1, 1, are the side bars of an automobile frame of the Ford type. 2 represents the rear cross bar. Both the side bars and the cross bar are channel bars, the side bars having their channel opening inward and the cross bar having its channel opening downward. The cross bar extends beyond the side bars at theends, and is crossed at the ends-by an element of th! frame structure which in general ma 1 be reit'erred to as body member, 3, making an inwardly upwa by opening angle with. the upper surface oi the cross bar, 2. The

flanges of the cross bar, 2, finish at the ends of the bar in an upward and outward slope,

slightly curved, as seen at 2. 41 is the bracket or mount for securing a bumper which in general comprises a longitudinally extending bracket arm-ad apted to be applied across the end of the cross bar, 2, and ham ing an inwardly projecting lug, i which abuts and fits substantially upon the downwardly and outwardly :facing upwardly and outwardly eil'tending-'-sloping edgeZ, of the cross bar flange, the edge of the lug Specification of Letters Intent.

being rabbeted as seen at e to form a lip which engages the flange, 2 at the opposite side from that past which there is extended a clamping bolt, 6. This bolt is an ill-hook bolt having its hook, 6, engagedin the angle between the upper surface of the cross bar, 2, and the crosswise extending member, 3, The bracket arm, 4, is preferably made as shown with the main body consisting of a vertical web and liorisontal flange at the lower side. It has the obliquely extending boss, 4:, occupying the angle between the :vertical web and the horizontal flange at the outer side, and being somewhat extended at the inner side of said web. And this boss is bored to receive the stem oi the hook bolt, 5, in a direction which is transverse, and nearly at right angles, to the edge of the lug, 4a, which abuts upon the sloping edge, 29,-or5 the flange of cross bar, 2; so that the hook bolt having its hook member engaged, as stated, in the angle between the cross bar, 2, and the member, 3, extending through said lug and secured by the tightening nut, 7, clamps the lug, 4P tightly against the sloping edge, 2 and thereby opcrates for binding the bracket arm firmly against the end of the cross bar. At the opposite side of the cross bar from that at which the bolt is positioned, the brachet arm is deflected inward to reach the outer side of the side bar, 1, where it is provided with suitable lugs, e, l", for receiving the ends of a ii -bolt, 9, which clasps the side bar and is secured by tightening nuts 9, on its outer ends.

Any desired form t of inipactreceiving bumper may be secured to the lo'ngitudina extending bracket arm, a, which are vided with bolt holes, 4: "for that purn a. 6 represents a fragment oithe supporting arm of such an irn,.act receiving I claim i 1. in combination with an automobile frame having longitudinal side bars and a cross bar which joins them and which has at the end and under side an edge sloping up outwardly and a memberwhich crosses the end of the cross bar above the same, making an upwardly; and inwardly opening, angle therewith, a longitudinally extending racket arin having an inwardlyqnojecting lug which abuts and its substantially against said sloping edge and an ti-hooh bolt having its hook engaging said angle and a stem ex tending through the bracket arm in a direction transverse to said slope, and tightening means on the end of the bolt.

2. In eomlnnation with an automobile frame having longitudinal side bars and a cross bar which joins them and which has at the end and under side an edge sloping up outwardly and a member which crosses the end of the bar above the same, making an upwardly and inwardly opening angle therewith; a longitudinally extending bracketarin secured to the side bar and extending thence past the edge of the cross bar and having an inwardly-proj(acting lug which abuts and fits substantially against said sloping edge, and an Lhoolc bolt having its hook engaging said angle and itSSlJt-HII extending through the bracket arm in a direction transverse to said'slope, and attaching means on the end of the bolt, the transverse bar of the frame being a flanged bar, and a vertical flange thereon having the sloped edge, the lug being rabbeted at its edge abutting on said slope to form a lip which engages at the opposite side of said flange of the cross bar from that pastwhich the bolt stein extends.

In testimony whereof I have hereunto set my hand at Chicago, Illinois, this fifth day of August, 1920.
